Chris,I had a very minor 2000 sq ft tenant space remodel that the county made us install auto-shutoffs because the shopping center was over 5000 sq ft. 505.2.2 is the perfect example of people thinking others aren't smart enough to turn off the lights.
Is your administrative section in the IECC same or similar to this requirement?
